It is an encoder, one of the plugins will encode multichannel to LtRt.

I tried it up against the Neyrinck, 5.1 to LtRt and my feeling was that some of the punch and brightness was lost after the stereo encoding on the DTS.

Maybe because of the different limiters?

Anyhow I'm sticking with the Neyrinck, your mileage may vary.

I thought the upmixers did a good job, but are very center heavy.
Probably great for upmixing full program, but not so great for music & FX that have to sit behind dialogue.

I wish they would make a DTS Headphone plugin and the DTS loudness tools as plugs.
